Title: Process for recovering monomer from polyethylene naphthalate by using low-pressure methanolysis
Inventor: ANDREWS A NAUJOKAS
IPC: C08G63/88
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a process whereby polyethylene naphthalate scraps are depolymerized to give a monomer component usable for producing another polyester. SOLUTION: An alcohol vapor is caused to pass through a melt of an oligomer of polyethylene naphthalate in a reactor to depolymerize the polyester to generate a dimethyl-2,6-naphthalenedicarboxylate monomer and a glycol monomer. These monomers are removed from the reactor by the stripping action of the alcohol vapor. The alcohol vapor is heated to 250-290 deg.C, and the monomers are generated under a pressure between the atmospheric pressure and the vapor pressure of the alcohol. The velocity of flow of the alcohol vapor is 2-10ft/min in terms of surface vapor velocity under standard conditions.

Title: Multiplex switching regulator
Inventor: KIMOTO AKIJI
IPC: H02M3/335
Filed: 1980-02-14
Abstract: PURPOSE:To prevent a switching element from being destroyed by a method wherein any one of the switching elements on the primary side is turned off in proportion to an increase in output current or a reduction in output voltage in a multiplex switching regulator. CONSTITUTION:Switching elements 2, 3 in a square-law type switching regulators are used to chop an input voltage 1 with a phase difference by 180 deg. so that square waves with differentiated phases by 180 deg. are generated on the secondary side of transformers 8, 9. The square waves are converted into DC current by a rectifier smoothing circuit consisting of diodes 10, 11, a reactor 13 and a capacitor 14 to supply DC voltage to a load 15. A pulse width controller 16 controls 'on' time during which switching elements 2, 3 are turned on so that the output voltage Vo can be maintained constant. The controller works to turn off the switching element 3 when the output current exceeds the specified limit, or when the output voltage becomes lower than the specified limit, to permit the element 2 only operates.

Title: Image processing system and its processing method
Inventor: SAKAI YASUMASA
IPC: H04N1/00
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To improve the system reliability by transferring communication log information generated by a facsimile equipment to a computer side. SOLUTION: An MPU 16 of a FAX 10 side uses a RAM 13 to apply compression such as MH or MMR to an image, and an NCU 11 makes dialing of a destination FAX number and communication is started. The time is obtained by a clock chip 15 and stored in the RAM 13. When the communication is finished, the communication log information is generated and stored in the RAM 13. Simultaneously the communication log information is sent from a bicentronics connector 12 of the FAX 10 side to a bicentronics connector 21 of a PC 20 side via a bicentronics cable 30. On the other hand, when the PC 20 side receives the communication log information, an MPU 24 edits the information and writes the result to a hard disk device 22 as a communication log file. Since the time at the FAX side is used to unify the communication log, the correspondence of the PC side for the PC side is automatically taken.

Title: Pneumatic radial tire
Inventor: NAKAMURA HIROSHI
IPC: B60C15/06
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To efficiently suppress separation in the radially outer end part of the outside layer where the radially outer end is located on the radially outermost side. SOLUTION: Since a coating rubber in the radially outer end part (low modulus area 18a) of a return part 16 is made of a rubber of low modulus, stress in the radially outer end part of the return part 16 is reduced, and thus the stress acting on a crack at the time when the tip of the developing crack has reached the low modulus area 18a, is reduced. As a result, even when the crack tends to develop in the circumferential direction, such development of the crack is effectively suppressed.
